I'm try to put B6 OEM S4 Avus 18" Wheel on B5 S4, anyone knows will fit or not fit???

You can find the spacers & lugs at tunershop.com.

You can also find replica 18" s4 wheels at a couple places on the net and you don't need spacers or lugs. probably cheaper this way if you don't care if they're OEM.

1.5 Santorin S4

I happen to come across the s4 18" replicas at victoriatire.com w/ audi centercaps for $165.00 a wheel but they offer no packages.

I would suggest going to edgeracing.com and picking up tires. You can get better tires this way anyway.

I was thinking about picking some up this week.
